D&D 5E Another addition of the Lost mine of phandelver

In the city of neverwinter, a dwarf named Gundren Rockseeker asked you to bring a wagonload of provisions to the rough-and-tumble settlement of Phandalin, a couple of days' travel southeast of the city. Gundren was clearly excited and more than a little secretive about his reasons for the trip, saying only that he and his brothers had found "something big" and he'd pay you ten gold pieces each for escorting his supplies safely to Barthens Provisions, a trading Post in Phandalin. He then set out ahead of you on horse, along with a warrior escort named Sildar Hallwinter, claiming he needed to arrive early to "take care of some business."
You've spent the last few days following the high road South from NeverWinter, and you've just recently veered east along the triboar trail. You've encountered no trouble so far,
but this territory can be dangerous. Bandits and outlaws have been known to lurk around the trail.
